Russia’s invasion of Ukraine has highlighted once again that fighting does not just take place on the physical front lines. Since the early onset of the war, footage of burning enemy tanks, disillusioned Russian soldiers, and a lone heroic fighter pilot defending Kyiv were shared countlessly on social media, bolstering troop morale and mobilising public support.1 The use of information in warfare is nothing new: already during the Peloponnesian war between Sparta and Athens some 2400 years ago, the information space was exploited to deceive enemy forces, maintain troop confidence, and sway public opinion. An early military thinker, Sun Tzu, wrote in the sixth century BC that “the skilful leader subdues the enemy’s troops without any fighting,”2 highlighting the essential role played by non-lethal, information-related capabilities in achieving military outcomes.
